Shadow has summed up the most likely sequence of events IMO.
But long ago at the start of these debates I asked a question that has not yet been answered:
Do AF regularly flight plan Airbus ops at FLs where coffin corner conditions occur, and where safe flight with degraded automatics would be highly problematic?
If the answer is yes, then presumably other Airbus operators do the same.
That being the case I will no longer travel anywhere on an Airbus and will advise my friends and family to do the same.
